Abstract: 946,134. Selective printing. KIENZLE APPARATE G.m.b.H. Feb. 22,1961 [Feb.22, 1960 ; Feb. 3, 1961], No. 6453/61. Heading B6F. [Also in Divisions B4 and F2] A business machine comprising means for punching a card, carriage means movable in steps along a predetermined path, a motion control arrangement comprising a plurality of control members provided with recesses and projections arranged in predetermined patterns on the members, programme means associated with the carriage means to selectively position a number of the control members at each step, in dependence on the position of the carriage means, in effective positions wherein sensing means are provided for sensing one recess or projection on each of all the selected control means simultaneously in dependence on the momentary relative position of the selected control members and the sensing means controls the movement of card transporting means and/or the selection of the punching means in accordance with the positions of the recesses and projections on the selected control members. In the accounting machine shown, the feeding of cards to be punched and the selection of the punches are controlled by means of tabs on a replaceable programme carriage 72 connected to and movable with the tabulating carriage 214 of the machine. The stepwise feeding of each card is effected by means of a slide carried by a rack bar 18 which also carries a bracket 51 having projecting therefrom a shaft 52 on which is turnably mounted a spring- influenced member 53 which includes an arresting means 54 co-operable with a ratchet bar 56 and sensing means 55 which extends across a set of bars 57 and a clearing bar 75. The sensing means sense aligned projections and recesses in the bars 57 when the bars are in their lower position, the recesses of successive bars being arranged in binary code and the beginning of the first recess on each bar coinciding with the end of a recess on a preceding bar. The bars are operatively connected to bars 70 which sense tabs 71 on the carriage 72. The cards are punched by means of rows of punches 87 operable by projections 89 of hammers 88 each of which is shiftable along the respective row of punches under the control of members 206, Fig. 5a, which sense a pin carriage 202. The heads 90 of the hammers are located between the punches and a camoperated slide 91 which is mounted for horizontal movement on a U-shaped bridge member 163 which is vertically reciprocable by means of connecting rods 162 connected to eccentric members 161 mounted on a shaft 146 which is driven from a motor 140 through a one-way coupling (see Division F2). The selection of the punches to be actuated is determined by the position of the slide 91 which has cut-outs 92, 93, Fig. 3, and is operatively connected to a plate 97. The cut-out 92 is used to effect punching by the punches 87. The teeth of a stationary bar 116 are engageable by the arresting means 117 of a spring-influenced member 118 which has sensing means 119 extending across control bars 114 and a clearing bar 111. The means 119 senses aligned projections and recesses of the bars 114 when the bars are in their upper position, the bars being similar to the bars 57. The bars 114 are operatively connected to bars 124 which sense tabs 125 on the carriage 72. The cut-out 93 in slide 91 is used to effect punching by punches 166, Fig. 5b, of extra holes denoting plus, minus and sum symbols. The punches co-operate with camoperated spring-influenced hammers 168 which have sensing teeth 169 engageable by control bars 170 and further control bars 171, 172. The bars 170 are similar to the bars 57 and 114 and are operatively connected to bars 186 which sense tabs 185 on the carriage 72. The bars 171, 172 are controlled by electromagnetic means 183, 184 energizable by tabs on the carriage 72. The punches 87 may be replaced by printing members, the punching hammers 88 being then used for impression of the printing members. Specification 844,501 is referred to.
